Top 10 SEHS IA Ideas That Are Actually Interesting (and Score Well)

• Why It Works: Easily executable and ties directly to flexibility and muscle readiness.
• IB Concepts: Joint mobility, flexibility, muscle elasticity.
• Use RevisionDojo for: Flashcards on types of stretching and plyometrics, practical experiment design.

5. Reaction Time and Sleep Deprivation

• Why It Works: Taps into cognitive and neuromuscular domains.
• IB Concepts: Central nervous system, fatigue, and alertness.
• Use RevisionDojo for: Sleep science notes, reaction drills, and ethical data handling with peers.

6. Dominant vs Non-Dominant Hand Strength

• Why It Works: Easily measurable, simple equipment (dynamometer), high control.
• IB Concepts: Muscular strength, laterality, reliability in testing.
• Use RevisionDojo for: Test-retest protocols, muscle physiology, and gender considerations in results.

7. Resting Heart Rate Changes from 5-Minute Meditation

• Why It Works: Integrates mental health and performance—relevant, measurable.
• IB Concepts: Parasympathetic nervous system, heart control.
• Use RevisionDojo for: Notes on autonomic responses, and designing calm testing environments.

8. Effect of Footwear Type on 20m Sprint Time

• Why It Works: Focuses on biomechanics and friction—real-world relevance.
• IB Concepts: Frictional force, stride efficiency, muscle contractions.
• Use RevisionDojo for: Biomechanics flashcards, analysis of external factors (surface, shoes).

9. Gender Differences in Balance Test Performance

• Why It Works: Simple test, yet allows meaningful data analysis.
• IB Concepts: Motor learning, proprioception, center of mass.
• Use RevisionDojo for: Lab procedures on stork balance tests and interpreting balance outcomes.

10. Relationship Between Arm Span and Swim Time

• Why It Works: Connects anthropometrics to athletic performance.
• IB Concepts: Body proportions, levers in movement.
• Use RevisionDojo for: Notes on biomechanics, anthropometry, and fair testing.

Frequently Asked Questions (FAQ)

Q: What’s the ideal word count for my IA?
Aim for 1,500–2,000 words. Include appendices for raw data if needed.

Q: Should I pilot test my method?
Yes! Pilot testing improves your reliability and lets you troubleshoot issues before full data collection.

Q: Can I use classmates as subjects?
Yes, with consent and ethical design. Include ethics commentary in your write-up.

Q: Should I include references?
Yes, include at least 3–5 sources to support theory and method justification.
